We've all gone through school or have heard somewhere that flipping a coin gives an equal chance to land on heads or tails. Many sport matches begin with a coin flip. Some elections are decided by a coin flip. If you flipped a coin and got heads ten times in row, that would be very luck; the math would actually say you'd have a 1 in 1023 chance of making that happen.
There are many things in life that you can attribute to luck, to chance. When it comes to flipping coins, don't count on it. The weight of coins isn't distributed equally - most notably is the U.S. penny. When it comes to flipping a penny, studies have shown that heads does come up more often. Moreover, if you were to spin the penny on a table, it would rest with its tails-side up about 80% of the time.

There are many lucky instances in life that are difficult to attribute to a line of logic. Flipping coins isn't one of them. It wasn't luck. It was simple physics.
